This invention has relation to a device for making stufied pastry, suchas ravioli, filled confectionery and other similaralimentary products. Y1

The object or" my invention is the provision of a hotter grade oi?articleoi' the hind referred to, and also to produce such article at alower cost than has heretofore heen found possible; To this end myinvention consists in the hereinafter hilly explained dud illustrated inthe appended drawings, or? wh ch: J

TllEdBVlC'E 1 am about to describe de signed to manufacture raviolihutma as shove stated, he adapted to the ptwduction oi other stuhedalimentary erticlee. "he indicated in Fig. 1 paste oftheproper consisteny is delivered to sets ofroliers and 8 from two hatches 1 and 2,which hetches in the first instance have been deposited on stationerytables 3 and d by the naachineoperator. in passing through these rollersthe paste is formed into sheets 9, 10,'oi the correct thickness. Whileonly two sets'ot calibrating rollers are here shown, heceuse two setssufice in a narrow machineplwisli it understood that. more sets ofrollers will he required in wide machines cepahle of producing long rowsof ravioli at one time,

forms no part of the not herein shown. Centrally located, above therollers 11, 12, 1s a suitable hopper 20, into which stufing material 21is deposited. This hopper may be cylindrical in shape, or it may heoblong in a wider machine. It has no bottom but is provided with curvededges 20, 20 which edges are substantiallyconcentric with the rollers11, i2. lhe edges are set so close to the periphery of said rollers,that the sheets of paste almost scrape against the edges in passing.'lhe paste sheets may properly-he said to form the bottom of the hopper,and do form such bottom, as will presently appear;

The construction of the rollers 11, 12 is very important, because notonly is each piece of ravioli formed between these rollers, but they arealso separated and their edges pressed together in passing through thetwo rollers, as-will now he explained. Ravioli is made in difierentshapes. I prefer to shape the pieces as indicated in Figs. 2 and 3, insquares, be-

present invention it is cause they may be made in such shape withoutwaste of material. Each square is provided with a studed center portion,and this center may he c'i rcular or square, as desired. it find thesquare mold most economical to manufacture, and the machine hereinillustrsted. is provided with such square molds. Referring to Fig. 4 itis seen that the roller 11 is made with a seriesof rows of molds, 1111*, there being in this case two molds in each row. The roller 12 isprovided with periphferal, 'nnular cutters, 13 and 14;, and thesecutters a e shaped to slit'the paste sheets length- "wise as they passbetween the rollers. On the roller 11 is mounted transverse rows ofcutters 15, 16. It is important to note that, when the machine is inoperation, these axially disposed cutters pass between the peripheralutters of the roller 12'.

ill

In operation the pastesheets and the form ters in such a manner, thatthe twelve pieces the result that the paste sheet 9 is forced into themolds 11, 11 and the space thereby created is filled with the samestufiing which depressed the aste. The two rollers 11, 12 are adjustablyxed so close together that the two sheets of paste are very firmlypressed together, and no more stufiin g is able to crowd between thesheets than that which has lodged in the cavities of the molds. The,stuflin is a thick, plastic composition. It does not ow very readily.And as the sheets of paste touch the bottom edges of the hopper, thereIS no danger of any stuffing working its way between the paste and saldedges.

For family use cans capable of holdlng twelve pieces of ravioli, andfilled with sauce, are usually employed. The form rollers 1s shownprovided with six rows of molds. there being two molds in each row. Theordinary can of this capacity is large enough to receive the two piecesof ravioli of each row. As a consequence enough pieces are formed ateach revolution of the rollers 11, 12 to fill a can. The paste isdiflicult to handle and can only be successfully manipulated at veryslow speed. The rollers 11, 12 should not make more than five to tenrevolutions per minute. As a consequence ample time is afforded theconveyor to move forward step by step as each can isfilled.

Even after the pieces of ravioli have been completely formed andseparated 1t 1s diflicult to keep them from adhering to one of therollers. A series of suitable scrapers, 60, may be applied to the roller12, and they may successfully dislodge and keep this roller free i fromadhering pieces or fragments, but on account of the molds 11 11 and theaxial cutters 15, 16 such scrapers cannot readily be applied to theroller 11. In case the paste P used shows a tendency to stick to therollers it is well to modify the proportions of the cutof ravioli foreach can are not entirely separated, but remain tied together in a strip17 two pieces wide and six long, by a very thin film of paste. Theweight of the free portions of this strip will help to dislodge any unitof the strip showing a tendency to stick to the rollers. In order toattain this result the cutters 13 and 15 should project a trifle fartherthan the cutters 14 and 16. The difference is so slight that it cannotbe brought out clearly in the drawings, but it is thought not difiicultto understand by anyone versed in the art, that the cutters 13 will trimthe edges of the strip and the cutter 15 will cut ofi the strip at eachrevolution of the rollers. As the strip sinks into the can, and strikesbottom, the pieces will commence to fold into an accordion shape, seealso the diagrammatic Fig. 6, "particularly if guidedbetween suitablegauges 22, 23. The subsequent cooking ii? the can and the later.handling of the cans suffice to separate the pieces that are not tornapart in falling into the cans.

Where the form rollers are twice the diameter there willbe twelve rowsof molds, and two diametrically opposed cutters 15 would be required, inorder to deliver twelve pieces of ravioli in each can. My aim is topoint out that, given a certain capacity of production per minute, and acertain width of machine, there is a fixed relation between cutters andmolds, even as the timing of the movement of the conveyor has a fixedrelation to the rotation of the form rollers.

A referred construction of the roller 11 is in icated in Fi 5. Theroller is shown made in five sections, and the sections are shown searated on the roller shaft, for the sake of c earness. There are twoouter sections 30, 31, which maybe exactly alike but assembled inreverse relation. Inside of these are two intermediate sections 32, 33,which also may be identical in sha e. In the center is a section 34, ortwo sectlons 31 may be assembled, the opposite way, an used as a center.The advantage of this construction is that, in making the roller, onlysimple turning and milling operations are emplgyfd, as against-theexpensive 0 eration of si 'ng molds into the surface 0 a solid roller.Those versed in the art will readily appreciate, that the rollers 12similarly may be made in four sections, of which the two end sections 12and the two center sections- 12 may be respectively alike.

The cutters 13, 14, 15, 16 are preferably made crimped, as indicated inthe drawings,

part1 because the appearance of the finished artic e is therebyimproved,and mainly for the reason that t e serrated edges of the comressedpieces of paste become looked very tightly together, and will not comeapart.

The device ofm invention may be driven from any suitab e source ofpower, not shown, and such power is. applied to rotate a drive shaft 40which, through suitable gearing, such as a chain 41, is connected torotate the roller 12 at the speed hereinbefore indicated. Rigidlycombined with the latter is a gear wheel 42, and this wheel drives anidentical ar wheel 43, of the roller 11. From the r0 ler 12 extendchains 44, 39 to the roll.- ers 5 and 8, and the roller-11 is similarlyoperatively connected with the rollers 6 and 7 In this manner all therollers are connected to be rotated continuousl at the proper speed.Chain gearing is s own for the sake of clearness and simplicity, but inactual practice I prefer to employ worm and spur gearing.

For the purpose of imparting properly timed intermittent movement to theconve or, an arm 45 may be fastened on the drive s aft 40. This arm ispositioned to strike a pin 46 of a bell-crank 47 and the latter carriesa spring-held pawl 48, which in turn engages a ratchet wheel 49, of theconveyor shaft 50. The bell-crank is, by a spring 51, normally heldretracted a amst a suitable stop 52. As the arm 45 reac es the pin 46,it commences to swing the bell-crank and to turn the sprocket wheel,until a forward step of the conveyor has been effected,whereupon the armpasses the'pin, and the spring '51 is free to return the bell-crank toits normal position. A mechanism as.the one just described will advancethe cans, as required, but I wish to state that, in practice, I employmuch more elaborate devices in order to efiect a smooth, positivemovement to the conveyor. But as the particular means employed does notform part of this invention, I have shown one which can be easilycomprehend'ed by the reader.

Means, such as a weight 60, may be placed in the hopper in order toapply pressure on the stufling, sufiicient to force the latter into themolds 11, 11". More elaborate devices may be substituted but the simpleweight 60 is, perhaps, the most convenient, on account of its verysimplicity.

In lace of recessing on y one form roller the fu ll depth of thestufiing it is, of course, possible to sink the molds one-half thedistance into each roller, as indicated in'Fig. 6, where the'rollers70,, 71 are provided with shallow half-molds 7 0 and 71. The cutters 72,73 may remain exactly the same as the cutters 15 and 16. OneobJection'to this construction is the additional expense of the secondset of molds, and little is'gained, un

less the appearance of the finished article is the main consideration.

I claim: j

1. In a ravioli machine, a cuttin roller comprising, a lurality ofcylindrical sections and circn ar knives of a larger diameter betweensaid sections; in combination with a second roller comprising, a seriesof cylindrical sections having convex annular beveled edges and a seriesof cylindrical discs fitting between said sections, the periphery ofsaid discs having transverse grooves the edges of which are beveled tocorrespond with the annular convex bevels of the roller, and axialcutters seated between said grooves and fitting between the circularknives of the first named roller.

'2. In a ravioli machine a pair of intergeared rollers, means forformlng and feeding sheets of flour paste to said rollers, an

ing to the paste sheets on said rollers, t e bottom edge of said hopperbeing shaped to conform to the contour of the rollers, means on therollers for cutting the stuffed paste sheetsf into s uares, one or bothof said rollers bein provi ed with deep square molds into whic thestufied paste is free to enter, there being between said molds and thesaid. cutting means broad peripheral margins between which the pastesheets become rmly pressed together and the stufling expelled from thesemarginal portions.

3. In a ravioli machine, a pair of intergeared rollers provided withindented molds and having annular and axial cutters separating saidmolds, there remaining a substantween said molds, the other roller beingmade with annular per pheral cutters adapted tobe positioned between themolds. of the first named roller at the point of contact of the rollers,all the molds being s aced apart so as to provide a wide margin etweenthe Y cutters and the molds, means for feeding sheets of flour paste tothe rollers, and a detachable open bottom hopper for guiding stalling tothe paste sheets on the rollers.

5. In. a ravioli machine, a pair of intergeared rollers provided withindented molds and having annular and axial cutters between said molds,there being a substantial peripiseral margin between the cutters and momeans for feeding sheets of paste tothe rollers, an open bottom hopperwith vertical sides above said rollers for iding stufiing to the pastesheets on the rol ers, and means for ad usting said hopper vertically toaccommodate paste sheets of various thicknesses.

In testimony whereof I have hereunto affixed my signature.
